Description
Technical Field
[0001] The utility model relates to the technical field of supporting structures in foundation pits, and more specifically, to a supporting structure in foundation pits which is easy to assemble and disassemble. Background Art
[0002] The support structure that is easy to disassemble and assemble in the foundation pit usually refers to the internal support system, which constitutes a key part of the foundation pit support system and is used to stabilize and assist in force transmission. When the cantilever retaining structure cannot bear the pressure of the soil on the side wall of the foundation pit alone, the internal support structure becomes an important line of defense, effectively supporting and stabilizing the foundation pit and preventing soil deformation and collapse. This support structure is not only reasonably designed, but also easy to disassemble and assemble, which greatly improves construction efficiency and safety. In existing foundation pit support projects, it is a common practice to use fixed rods to support the support plate. This method ensures the stability and safety of the support structure. However, when the support plate needs to be disassembled, this fixing method brings inconvenience. Workers need to carefully remove the bolts on the support plate one by one. This process is not only time-consuming, but also increases the complexity and difficulty of the operation. In today's pursuit of construction efficiency and safety, this disassembly method obviously can no longer meet the needs of modern engineering. Utility Model Content

[0024] A rotating disk 21 is fixedly mounted on the outer surface of the threaded sleeve 7 , and a handrail 22 is fixedly mounted on the outer surface of the rotating disk 21 .
[0025] The staff slowly places the two support plates 1 into the foundation pit, and then holds the threaded rod 6 and the threaded sleeve 7, and adjusts the distance between the threaded rod 6 and the threaded sleeve 7 according to the distance between the two support plates 1, and drives the rotating block 14 inside the fixed seat 2 through the threaded rod 6. When the threaded rod 6 rotates inside the threaded sleeve 7, when the distance is adjusted to a suitable distance, slowly put the sliders 3 at both ends of the threaded rod 6 and the threaded sleeve 7 into the fixed seat 2, and fix the sliders 3 through the fixed seat 2, and then hold the handrail 22, and drive the threaded sleeve 7 and the handrail 22 to rotate synchronously, so that the threaded sleeve 7 rotates on the outer surface of the threaded rod 6, and again, reinforce the two support plates 1, thereby completing the support of the two support plates 1.
[0026] Slowly put the two support plates 1 into the foundation pit, then hold the threaded rod 6 and the threaded sleeve 7, adjust the distance between the threaded rod 6 and the threaded sleeve 7 according to the distance between the two support plates 1, rotate the threaded rod 6 inside the threaded sleeve 7, and when the distance is adjusted to a suitable distance, slowly put the sliders 3 at both ends of the threaded rod 6 and the threaded sleeve 7 into the fixing seat 2, fix the slider 3 through the fixing seat 2, and facilitate the support of the two support plates 1 through the cooperation between the threaded rod 6 and the threaded sleeve 7. Compared with the traditional structure, this structure facilitates the disassembly of the threaded rod 6 and the threaded sleeve 7 through the cooperation between the fixing seat 2 and the slider 3. Installation, at the same time, through the cooperation between the threaded rod 6 and the threaded sleeve 7, it is convenient to support the two support plates 1. The connection method of the threaded rod 6 and the threaded sleeve 7 not only realizes the rapid and accurate connection between the support plates, but also avoids the complicated installation and tedious disassembly steps in the traditional support method, greatly shortening the construction period. The excellent stability and bearing capacity of the threaded connection between the threaded rod 6 and the threaded sleeve 7 ensure the stability of the support plate 1 under the action of soil pressure and lateral force, and effectively prevents the loosening or displacement of the support plate 1. In addition, its adaptability and flexibility allow the support structure to be adjusted and optimized according to actual needs to meet the support requirements of different construction stages.
[0027] The support plate 1 has a limit groove 20 formed inside, a limit plate 19 is movably installed inside the limit groove 20, an expansion plate 4 is fixedly installed on the top of the limit plate 19, and one end of the expansion plate 4 completely penetrates the support plate 1. A limit hole 5 is formed inside the expansion plate 4, and a box 17 is fixedly installed inside the support plate 1.
[0028] A limit block 15 is movably installed inside the limit hole 5, a pull rod 16 is fixedly installed at one end of the limit block 15, and the pull rod 16 completely penetrates the inside of the box 17, a spring 18 is installed between the box 17 and the limit block 15, and a pull ring 11 is fixedly installed at one end of the pull rod 16.
[0029] When the staff encounters a deeper foundation pit, it is necessary to increase the length of the support plate 1. By holding the pull ring 11, the pull rod 16 is pulled inside the box 17 through the pull ring 11, and the limit block 15 is pulled by the pull rod 16 to move inside the limit hole 5. The limit block 15 squeezes the spring 18 so that the limit block 15 slowly disengages from the inside of the limit hole 5. Now, by holding the extension plate 4, the extension plate 4 drives the limit plate 19 to move slowly inside the limit groove 20. The extension plate 4 is limited by the limit plate 19, which avoids the direct removal of the rotating block 14, thereby completing the increase in the length of the support plate 1.
[0030] When encountering a deeper foundation pit, it is necessary to increase the length of the support plate 1, by holding the pull ring 11, the pull rod 16 is pulled inside the box 17 through the pull ring 11, and the limit block 15 is pulled by the pull rod 16 to move inside the limit hole 5, and the limit block 15 squeezes the spring 18 so that the limit block 15 slowly leaves the inside of the limit hole 5, and now by holding the expansion plate 4, the expansion plate 4 drives the limit plate 19 to move slowly inside the limit groove 20. Compared with the traditional device, the device facilitates the expansion plate 19 to move slowly through the cooperation between the limit block 15 and the pull rod 16. 4 and the limit plate 19 are slowly inside the support plate 1, so that the support area of the support plate 1 is increased by the expansion plate 4, which can effectively improve the stability of the support structure, so that the support plate 1 and the expansion plate 4 can better disperse and withstand the soil pressure and lateral force, thereby ensuring the stability and safety of the foundation pit, and can also significantly enhance the bearing capacity of the support structure, so that it can adapt to more complex and changeable construction needs, especially in places with complex geological conditions or low soil bearing capacity. The increased area of the support plate 1 is also helpful to reduce the settlement and deformation of the foundation pit, which has a positive effect on protecting the surrounding environment and building safety that cannot be ignored.
[0031] A mounting seat 13 is fixedly installed on the inner side of the support plate 1 , and a tool box 12 is fixedly installed inside the mounting seat 13 .
[0032] The staff holds the tool box 12 and slowly places the tool box 12 into the interior of the mounting base 13, and fixes the mounting base 13 through the tool box 12. The flexible installation and disassembly characteristics of the tool box 12 greatly improve the construction efficiency. The staff can quickly install or remove the tool box as needed to perform various repairs, adjustments and construction work in the foundation pit without the need for additional installation or disassembly steps, saving valuable time and manpower.
[0033] A fixing plate 8 is fixedly installed at the bottom of the support plate 1 , and positioning holes 9 are provided inside the fixing plate 8 , and the number of the positioning holes 9 is set to six.
[0034] By slowly nailing the positioning column into the positioning hole 9, the fixing plate 8 is fixed by the positioning column, and then fixed by the fixing plate 8, the shaking of the support plate 1 when supporting the foundation pit is avoided, and at the same time, the stability of the support plate 1 during the supporting process is guaranteed.
[0035] Among them, a reinforcing rib 10 is fixedly installed at the angle between the support plate 1 and the fixing plate 8, and the reinforcing rib 10 is in a triangular shape.
[0036] Since the reinforcing ribs 10 are in a triangular shape and the triangle is stable, the support plate 1 is more stable when supporting the foundation pit, the shaking is reduced, and the use efficiency of the support plate 1 is improved.
[0037] The inner diameter of the support plate 1 is equal to the outer diameter of the extension plate 4 , and both the extension plate 4 and the support plate 1 are made of stainless steel.
[0038] Since the inner diameter of the support plate 1 is equal to the outer diameter of the extension plate 4, it is convenient for the extension plate 4 to move slowly up and down on the support plate 1. The support plate 1 and the extension plate 4 are made of stainless steel, and the stainless steel extension plate 4 and the support plate 1 can remain stable for a long time in a humid and complex underground environment. Their high strength and tensile strength ensure the firmness and safety of the support plate 1 and the extension plate 4.
[0039] The working principle and use process of this utility model:
[0040] The staff slowly places the two support plates 1 into the foundation pit, and then holds the threaded rod 6 and the threaded sleeve 7, and adjusts the distance between the threaded rod 6 and the threaded sleeve 7 according to the distance between the two support plates 1, and drives the rotating block 14 inside the fixed seat 2 through the threaded rod 6. When the threaded rod 6 rotates inside the threaded sleeve 7, when the distance is adjusted to a suitable distance, slowly put the sliders 3 at both ends of the threaded rod 6 and the threaded sleeve 7 into the fixed seat 2, and fix the sliders 3 through the fixed seat 2, and then hold the handrail 22, and drive the threaded sleeve 7 and the handrail 22 to rotate synchronously, so that the threaded sleeve 7 rotates on the outer surface of the threaded rod 6, and again, reinforce the two support plates 1, thereby completing the support of the two support plates 1.
[0041] When the staff encounters a deeper foundation pit, it is necessary to increase the length of the support plate 1. By holding the pull ring 11, the pull rod 16 is pulled inside the box 17 through the pull ring 11, and the limit block 15 is pulled by the pull rod 16 to move inside the limit hole 5. The limit block 15 squeezes the spring 18 so that the limit block 15 slowly disengages from the inside of the limit hole 5. Now, by holding the extension plate 4, the extension plate 4 drives the limit plate 19 to move slowly inside the limit groove 20. The extension plate 4 is limited by the limit plate 19, which avoids the direct removal of the rotating block 14, thereby completing the increase in the length of the support plate 1.
